Command Prompt on Window version

Just installed the 8.0 version for Windows. As a Unix guy, I
would like to do things through the command prompt. I have
trouble to bring up it. After bringing up the "psql to
template1" as the same user of the installation
configuration, it disappears right after I type in the password.

How to bring up the command prompt correctly? Also, is a way
to bring it up with a different user from the user in configuration?

Start->All Progams->Accessories->Command Prompt

Then just do "cd":s into the pgsql directory.

To bring it up as a different user use:
runas /user:<username> cmd.exe
